Having just returned home from visiting the pilot in hospital, i think i should write from our recollection ( the pilot and myself as the passenger ). We were on late final waiting for the trike in front of us to vacate the runway, once he cleared the runway and gave his call, we commenced our decent , as we started to round out we drifted to the left, i don't know if it was wake turbulence or wind drift or whatever but it was a smooth drift to the left, the pilot then tried to correct this to realign with the runway at which time we got thumped on the runway hitting the right tip of the wing and landing very hard . The motor then went to full power and we got launched in the air again. It seemed he was going to do a go around when he realized the motor was stuck at full throttle, he said he was going to do an emergency landing, killed the motor and commenced our decent for landing. At this point all seemed fine to me, when we were about 50", the trike stalled, the nose and the right wing dropped and then we hit the ground and slid across the surface coming to a stop. Everything happens so quick you can't do anything. When i spook to the pilot in hospital, it really shocked me that he said when we took of again for the go around that apart from no throttle control he also had very little pitch and roll control. I don't know what caused this but i guess we were in the hands of the man upstairs. The pilot sustained a broken pelvis and i just had muscle soreness all over but mainly to my leg where i got pinned under the trike. I'm ok now but the pilot has had a plate inserted to his pelvis and will be some time before he recovers from his injuries. Despite what he is going through, he remains in good spirits.
